If in any case my action in filling dwindle into mechanical or semi-mechanical, done with little or no adverting of the mind to its performance, it so far becomes an involuntary action. But, if every voluntary action be performed for the sake of its consequences, then in every voluntary action there is comparison and judgement. Every such action proceeds upon the apprehended truth of some proposition. The mind decides "this is good" or "desirable;"Chapter nd immediately upon that decision, if accompanied with a persuasion that we are competent to accomplish this good or desirable thing, the limbs proceed to their office. The mind decides "this is better than something else;" either wine and cordials are before me, and I choose the wine rather than the cordials; or the wine only is presented or thought of, and I decide that to take the wine is better than to abstain from it. Thus it appears that in every voluntary action there is preference or choice, which indeed are synonymous terms.
This full elucidation of the nature of voluntary action enables us to proceed a step further. Hence it appears that the voluntary actions of men in all cases originate in their opinions. The actions of men, it will readily be admitted, originate in the state of their minds immediately previous to those actions. Actions therefore which are preceded by a judgement "this is good," or "this is desirable," originate in the state of judgement or opinion upon that subject. It may happen that the opinion may be exceedingly fugitive; it may have been preceded by aversion and followed by remorse;Chapter ut it was unquestionably the opinion of the mind at the instant in which the action commenced.
It is by no means uninstructive to remark how those persons who seem most to have discarded the use of their reason have frequently fallen by accident, as it were, upon important truths. There has been a sect of Christians who taught that the only point which was to determine the future everlasting happiness or misery of mankind was their faith. Being pressed with the shocking immorality of their doctrine, and the cruel and tyrannical character it imputed to the author of the universe, some of the most ingenious of them have explained themselves thus.
